Note: A servo motor should be powered from a suitable 5V-class supply capable of handling its current demand. When used with an Arduino or similar controller, the servo’s power should generally come from an appropriate external supply rather than relying on the microcontroller’s 5V pin for higher-load operation. Do not exceed the servo’s rated voltage.
